Home Battery Subscription: Affordable Home Energy Storage and Backup Options

Have you ever wanted a home battery that could power your critical loads or even your entire home, but you didn't want to pay the thousands of dollars upfront to make that happen? If that's you, there's a new option to "subscribe" to a home battery.

Palmetto Solar has launched a residential battery lease plan. You can call it Battery-as-a-Service. This program brings a reliable battery to your garage for as low as $98 per month with no large upfront investment required. The program is now available across 25 states, including key markets such as Arizona, California, Texas, Pennsylvania, Illinois, and Oregon. It gives homeowners a practical way to modernize their home energy setup without the heavy capital outlay.

Reliable Backup and Everyday Savings

The primary benefit is peace of mind during outages. A home battery provides automatic whole-home resilience, keeping your lights on, appliances running, and family comfortable when the utility grid goes down.

Beyond backup, the battery supports basic energy arbitrage. You charge it from the grid during lower-cost off-peak hours and discharge it to meet your needs during expensive peak times. Even without solar panels, this approach can produce roughly $600 to $1,000 in annual savings based on seasonal rate changes. These savings help offset much of the subscription cost, making robust blackout protection far more affordable.

Amplifying Value with VPP Programs

Enrolling your battery in a utility Virtual Power Plant (VPP) program, where available, can further reduce your net costs. During high-demand periods, utilities pay you for discharging energy back to the grid. This provides additional earnings for you while briefly supporting broader grid stability.

Maximum Benefits: Pairing with Solar

The strongest financial returns come from combining the battery subscription with rooftop solar and smart time-shifting. This is especially advantageous in markets with Net Energy Metering (NEM) policies, such as California's NEM 3.0, where standard daytime exports offer limited compensation.

By storing daytime solar energy and using or exporting it during high-value periods (for example, the premium evening peak hours between 6 PM and 8 PM in August and September), homeowners can generate thousands of dollars in annual credits and savings. This optimized setup often delivers net positive returns that exceed the subscription cost.

Strategy and Savings Breakdown

Operating Strategy	System Requirements	Estimated Annual Savings / Revenue	Net Benefit to Homeowner
Base Arbitrage	Grid connection only	$600 to $1,000	Subsidized blackout protection plus bill savings
VPP Integration	Grid connection, VPP enrollment	Variable based on events	Lower net lease cost
Optimized Solar Export	Solar array, VPP, time-shifting	Thousands of dollars in credits	Net annual profit

We face the real challenges of legacy energy infrastructure while believing firmly in superior decentralized solutions. For homeowners, a Palmetto battery subscription delivers immediate resilience, meaningful bill savings, and strong long-term value. Through smart software, home batteries, and supportive policies, families can take greater control of their energy needs and build a more reliable future.

Tesla Production: 2026 Half Way

Mid-Year Musings on the Manufacturing Mix

We have officially crossed the midpoint of 2026, and the production numbers for Tesla are officially in. Back in January, we looked at the persistent production plateau that characterized the vehicle market and wondered how the plug-in pioneer would navigate the lack of near-term volume catalysts. The actual results for the first half of the year reveal a total of 860,144 vehicles produced, split between 408,386 units in Q1 and 451,758 units in Q2. It is a fascinating data set that demonstrates why raw spreadsheet formulas lack real-world vision.

Statistical Surges and Trend Tumbles

When we mapped out our 2026 production models at the beginning of the year, the automated spreadsheet tools were screaming for an immediate return to exponential growth. Statistical algorithms look at long-term historical data and blindly project curves upward without any concept of factory retooling, engineering hurdles, or macroeconomic headwinds. Here is how those automated trend models and my estimate stacked up against Tesla's actual first-half vehicle production:

Model / Method	Q1 2026 Estimate	Q1 Error %	Q2 2026 Estimate	Q2 Error %	H1 2026 Total Estimate	H1 Error %
LINEAR	467,028	+14.36%	473,121	+4.73%	940,149	+9.30%
Seasonal	479,950	+17.52%	507,127	+12.26%	987,077	+14.76%
TREND	506,914	+24.13%	519,125	+14.91%	1,026,039	+19.29%
LOGEST	545,723	+33.63%	567,094	+25.53%	1,112,817	+29.38%
CWC Estimate	432,000	+5.78%	440,000	-2.60%	872,000	+1.38%
Wall Street Consensus	~410,000	+0.40%	406,024	-10.12%	~816,000	-5.13%
Actual Production	408,386		451,758		860,144

Every single mathematical trend model overshot the mark. The LINEAR was the closest trend model, and it missed by over 80,000 units for the first half; Seasonal missed by nearly 127,000 units; and the hyper-bullish LOGEST model overshot reality by a staggering 252,673 vehicles. These automated frameworks falsely assumed that the first quarter would see massive growth, ignoring the reality that the opening quarter of the year is historically a weak period for automotive hardware.

The Calculated Clarity of CWC

This brings us to our custom CWC calculation, which proved to be a triumph of pragmatic, grounded analysis. While the automated algorithms were predicting anywhere from 940,000 to over 1.1 million vehicles for the first half, the CWC estimate stood firm at a conservative 872,000 units. The US EV market was still recovering from the end of the EV tax credit. The new vehicles from Tesla (Semi and Cybercab) wouldn't have any meaningful production in the first half. This will start changing and will be significant in 2027. Our custom model correctly recognized these brutal facts of the start of 2026:

• No near-term volume catalysts existed in the product pipeline, because the next-generation affordable models were still well over the horizon.
• Agonizingly slow manufacturing ramps are an inescapable truth for radical new vehicle architectures, which applies directly to the early stages of the Tesla Semi and the Cybercab.
• A disciplined quarterly expectation was required, which led to a relatively flat 1H estimate.

By factoring in real-world complexities instead of relying on sterile math, the CWC first-half estimate came within a microscopic 1.38% of the actual 860,144 vehicles produced. Q1 is seasonally a low delivery time of year, and Tesla experienced an even deeper dip than we estimated. Manufacturing and delivery had a rebound in Q2 and vindicated our grounded approach.

Wall Street Wisdom vs. Real World Volts

How did our internal forecasts stack up against Wall Street's finest institutional analysts? For the first half of 2026, market analysts kept their expectations heavily tempered; this pessimism paid off in Q1, where the consensus was pretty close. However, they remained stubbornly pessimistic in Q2 and that's not how it played out. Heading into mid-year, the Tesla-compiled consensus from 22 sell-side analysts set an exceptionally low bar of 406,024 deliveries for the second quarter.

Tesla crushed this, reporting a spectacular 480,126 deliveries and blowing past Wall Street expectations by nearly 74,000 cars. This massive delivery spike allowed the company to aggressively clear out the 50,000-unit inventory overhang that had accumulated during a sluggish first quarter. While Wall Street was caught flat-footed by surging regional demand in Europe and China, the actual production footprint of 451,758 vehicles tracked beautifully alongside our steady CWC expectations. One caveat here: analysts estimate deliveries; we've been looking at production, so it's a bit of apples-and-oranges, but Tesla can only deliver a vehicle that's been produced.

Looking Forward

What does this mean for the remainder of 2026? Tesla (as with most automakers) sells more vehicles in the second half of the year. For Tesla, historically they sell about 22% more cars in the second half. If 2026 follows this, Tesla will finish the year with 1,895,000 vehicles produced in 2026. This is not far from our January estimate of 1,812,000 for this year.

Final Volts

The automotive transition is never a perfectly smooth, linear climb. Legacy manufacturers continue to stumble through various electrification half-measures, while Tesla is navigating a temporary volume plateau while working on new vehicles, adjusting regional supply lines, and focusing heavily on long-term physical AI development. Spreadsheets can help us chart the boundaries of what is possible, but disciplined execution on the factory floor is what ultimately matters. Every electric vehicle rolling off the line represents a permanent reduction in tailpipe emissions into the air we breathe, a lower total cost of ownership, and a step toward true energy independence. By matching statistical discipline with engineering reality, we can see past the noise of Wall Street and continue marching toward a future free from fossil fuels.

EVs Are Winning

Electrified transportation is the present and the future.

If you open any mainstream automotive, tech, or business news site today, you are almost guaranteed to encounter a steady wall of worry: "EV demand is cratering," the headlines blare, "Legacy automakers pivot back to gas," the pundits chime. It's a beautifully orchestrated symphony of doubt, frequently manufactured by the classic Petroganda of the Oiligarchy or driven by the psychological traps we explored in our piece on How Cognitive Illusions Fuel EV Misinformation.

But here at Cars With Cords, we prefer to look past anecdotal showroom noise and check the hard telemetry. When you zoom out and look at global automotive data, a completely different reality emerges. 

The simple, unassailable truth becomes obvious: EVs are winning, and internal combustion is trapped in a permanent, structural tailspin.

The 2017 High-Water Mark

To understand exactly where we are going, we have to look at where we peaked. The absolute apex for pure internal combustion engine (ICE) passenger cars happened all the way back in 2017. That year, the world bought roughly 83 million purely gas and diesel-powered light vehicles.

Since then, despite global population growth and an expanding international appetite for mobility, traditional engines have never come close to recovering that high-water mark. We did not just hit a temporary plateau; instead, we cleared a structural cliff. As we noted in our deep dive into why Fossil Fuel Peak Demand Has Already Happened, technology transitions do not wait for permission. They accelerate because the new architecture is fundamentally more efficient, reliable, and economical.

To visualize exactly what this looks like, let's examine the data compiled from the International Energy Agency (IEA) and BloombergNEF, charting the actual trajectory from 2010 through our current 2026 baseline, and projecting out to 2032.

Deconstructing the "Comeback" Illusion

The pandemic accelerated a trend that had already started. Look closely at the minor bump on the graph in 2024. Legacy auto executives popped the champagne when they saw that brief tick upward to 58.1 million units, pointing to it as proof that "gas is back."

Don't fall for the trick. That was not a sudden renaissance for spark plugs, oil filters, and complex transmissions. It was merely the post-pandemic clearing of long-standing semiconductor and component backlogs, paired with an interim push into traditional hybrids by buyers waiting for local public charging infrastructure to mature.

Once those backlogs cleared, the momentum of the EV adoption S-curve could not be held back. By 2025, pure ICE sales slipped right back down to 54.5 million. This year, in 2026, we're on track for roughly 51.8 million units. Traditional gas-powered cars now account for barely half of the global passenger car market.

Why the Slide is Structural

This is not a cyclical downturn that a temporary drop in interest rates will fix. This is a classic market substitution pattern driven by unyielding economic forces:

• The S-Curve Has Left the Station: In the world's largest automotive market, China, plug-in electric vehicles just captured a record-smashing 62.9% market share. In fact, every single one of the top 16 best-selling vehicles is now a plug-in. What happens in the largest manufacturing market eventually cascades to Europe, North America, and the rest of the world.
• Relentless Battery Economics: As we tracked in Powering the Future: How Batteries Transformed from Phones to Cars, scaling battery cell production creates an aggressive Wright's Law learning curve. Upfront price parity between the average EV and legacy ICE platforms is arriving at scale, making the choice a pure financial no-brainer for mass-market buyers.
• The Death of R&D Spending: Global automakers have fundamentally turned off the financial spigots for internal combustion development. The remaining ICE vehicles on dealer lots are increasingly riding on aging, legacy platforms as corporate capital budgets are permanently diverted into software-defined EV architectures.

The View to 2032

Modeling a steady, conservative 6% compounding annual decline through the next few years puts the long-term trend into sharp focus. By 2032, global pure ICE sales are projected to dwindle to just 35.8 million units, representing a staggering 57% collapse from their 2017 peak.

Yes, there will be a long tail for gasoline. Captured politicians will push policies to keep gas stations operating for years to come. But the economic engine of the global auto industry has permanently shifted.

The next time someone tries to convince you that the electric transition has stalled out, show them the above graph. The legacy narrative might be full of static, but the data is crystal clear. Electrified transportation isn't just the future anymore; it is actively winning the present.

Enjoy Energy Independence

Upcoming Electric SUVs: 300-Miles+ of Family Fun

The Heavy Hitters

Walk into any parking lot, and it's clear that the SUV is a dominant American vehicle of choice. The market SUVs satisfy is simple: American families and lifestyle buyers demanding flexibility, an elevated ride height, expansive cargo capacity, and multi-row configurations. But pushing a large, heavy, boxy vehicle through the air takes an immense amount of energy. In the internal combustion world, that translates to high fuel bills and significant tailpipe emissions.

That's why electrifying this specific segment is so critical. Battery technology has made quiet, steady, incremental improvements year after year, gaining energy density while driving down production costs. Now, those cumulative advancements are allowing automakers to build large, high aero drag vehicles that can confidently cross the significant 300-mile-plus range threshold.

We’ve watched this evolution unfold firsthand. Having owned a 6-seat 2016 Tesla Model X for six years, I remember when a mid-200s range on a large utility vehicle was considered the absolute bleeding edge. You can read my full breakdown of how that early pack held up in our Model X 3-year ownership review. Today, the upcoming generation of electric SUVs is setting a completely new baseline for utility, range, and features.

Empowering Words: Strategies for Impactful Environmental Advocacy Writing

I've written over a thousand blog posts here on cars with cords, and I'm curious to know how effective they've been. I know that state legislators have reached out to me due to some of the things I've written; my local utility improved their VPP based on my feedback via this blog; I was invited to be the pro-EV voice on a local conservative radio show; and several of you have used my Tesla referral code for solar or an EV, so I know the message is getting through at least a little.

If I'm sticking with this quixotic quest for a green planet (one blog post at a time), I'd better audit my toolkit. Are my current tactics landing like a lead balloon, or do they just need a polish? What's the secret sauce for squeezing maximum impact from this humble corner of the web? My grand vision: gently nudging society toward a world humming on renewables, where the air doesn't taste like exhaust and the water won't dissolve your fillings. But here's the rub. Is the winning play to paint doomsday murals of floods, fires, and Armageddon if we don't pivot? Or to dazzle with dollar signs, showing how clean tech pays fat dividends? Or, dare I dream, to spin yarns of everyday heroes turning backyards into solar-powered utopias? Buckle up, buttercups. Today, we're dissecting where to pour my finite hours for the biggest splash.

Crafting Compelling Narratives: Effective Messaging in Environmental Activism Writing

Introduction

In an era where environmental challenges demand collective resolve, the written word remains a potent instrument for inspiring action. Authors and advocates wield language not merely to inform, but to transform passive readers into engaged participants. Effective environmental activism writing hinges on messages that resonate deeply, fostering a sense of agency and possibility. This essay explores key approaches to such messaging, evaluates their impacts, and identifies the most potent combinations. By prioritizing empowerment and optimism, writers can bridge the gap between awareness and tangible steps toward sustainability.

Varieties of Persuasive Messages

Environmental writing benefits from a diverse palette of messages, each tailored to evoke response without overwhelming the audience. These strategies draw from psychological insights and empirical studies, emphasizing benefits, connections, and progress over mere warnings. A structured overview reveals their strengths.

Message Type	Core Focus	Example Application	Supporting Evidence
Personal Relevance	Ties issues to daily life and locale	"Local solar initiatives in your community could reduce energy costs by $500 annually per household."	Yale studies show localized framing boosts engagement by linking to shared experiences[1].
Empowerment and Efficacy	Highlights actionable steps and proven outcomes	"Community petitions have secured 15% more renewable funding in similar regions; add your signature today."	Efficacy messages increase political participation through heightened hope[2].
Health and Well-Being	Stresses improvements in physical and mental vitality	"Cleaner air from reduced emissions correlates with 20% fewer respiratory cases in urban areas."	Health frames enhance universal appeal, driving behavioral shifts[3].
Economic Opportunities	Spotlights jobs, savings, and equity	"The clean energy sector now employs over 3 million in the US, with growth in underserved communities."	Economic narratives foster support across ideologies[4].
Shared Values and Norms	Aligns with family, community, or ethical principles	"Safeguarding natural heritage honors our commitment to future generations, as echoed by peers nationwide."	Value-based appeals normalize action via social proof[5].
Success Stories	Celebrates real achievements and innovations	"Reforestation projects in the US have restored 1 million acres, enhancing biodiversity and tourism."	Positive examples sustain motivation and counter doubt[6].

This table illustrates how varied messages can be deployed flexibly. Writers should select based on audience, blending elements for depth. For instance, economic opportunities paired with health benefits appeal broadly, as they address practical concerns while evoking care for well-being.

The Pitfalls of Fear and the Ascendance of Solutions

While vivid depictions of potential disruptions capture attention, reliance on fear often yields diminishing returns. Research indicates that such approaches can evoke emotional fatigue, prompting disengagement rather than resolve. Audiences exposed to repeated threats may experience a finite "worry pool," leading to apathy or denial^[7]. Worry, a milder concern tied to personal stakes, proves more predictive of policy endorsement than outright fear, which correlates weakly with supportive actions^[7].

In contrast, solutions-oriented narratives excel at galvanizing intent. Studies comparing catastrophic tales to those emphasizing remedies find the latter superior in fostering pro-environmental commitments. Solution-focused stories elevate motivational intentions by up to 25% more than dire scenarios, as they instill a belief in feasible progress^[8]. This shift avoids paralysis, instead channeling energy toward innovations like efficient energy systems that promise lower utility bills and enhanced resilience.

The Synergy of Hope, Efficacy, and Relevance

The most impactful strategy emerges from integrating hope with efficacy and personal relevance, creating a narrative arc that propels readers forward. Constructive hope, rooted in collective efforts and rising awareness, combines powerfully with efficacy, the conviction that actions yield results. Empirical analysis reveals this pairing explains 22% additional variance in policy support and 18% in behavioral intentions, surpassing isolated elements^[9]. When doubt is framed constructively, as acknowledgment of gaps that spur improvement, it amplifies hope's effect on mobilization.

Relevance anchors these dynamics, making abstract concepts immediate. A message like "Your neighborhood's wind projects not only cut emissions but also generate $1,200 in annual savings, securing healthier air for your children" weaves hope (future abundance), efficacy (proven savings), and relevance (local ties). Such combinations transcend demographics, boosting engagement across political lines by affirming readers' capacity to contribute^[2].

Conclusion

Environmental activism writing holds the power to reshape societal trajectories, provided it embraces messages of empowerment over apprehension. By drawing on personal relevance, efficacy, and hopeful solutions, authors can cultivate a readership primed for action. As stewards of this vital discourse, writers must refine their craft with evidence in hand, ensuring every sentence advances equity and vitality. The path to a thriving planet lies not in lament, but in lucid, inspiring prose that invites all to participate. Let us commit to this endeavor, for in well-chosen words, we forge enduring change.

Fossil Fuel Peak Demand Has Already Happened

A structural shift away from fossil fuels is underway. You can watch a video titled "The Age of Fossil Fuels is Dead" here. The central argument is that the age of fossil fuels is structurally concluding, driven not by daily news cycles or policy mandates, but by the relentless economic and thermodynamic superiority of modern, electrified technologies. The trend is already visible in several major sectors of the US and global economy, indicating a transition phase just before a rapid, systemic decline.

The Arc of the Trend

To understand the energy transition, one must shift focus from short-term fluctuations to the long-term historical arc of technological change. As the commentators emphasize, the key lesson is that the fundamentals of transition often proceed smoothly, even in the face of significant global disruptions like world wars, recessions, and pandemics [2:18]. The structural growth of fossil fuel demand has been absent for nearly a decade, settling into a plateau [0:36]. This current moment for fossil fuels is highly analogous to the transportation transition that occurred in the early 20th century.

Specifically, the current situation mirrors the transport sector around 1910 [3:37]. At that time, horses were dominant, yet the growth in transport demand was increasingly driven by the new automobile. Arguments from the ‘horse lobby’ that cars would merely be layered on top of the horse system, leading to more horses and more cars, sound strikingly similar to arguments made today that renewables will only supplement fossil fuels [4:12]. History shows that the horse population experienced a rapid decline within twenty to thirty years after 1910, a trajectory that analysts expect to see repeated in the fossil fuel system as it moves past its peak.

Economic Competitiveness and Sector Peaks

The transition away from older technologies is fundamentally rooted in economic competitiveness, or the cost per unit of work. The introduction of the Fordson tractor in 1918 provides a powerful historical parallel for the current energy revolution [5:07]. Henry Ford utilized assembly line technology to develop a robust, affordable tractor that gradually became more economical than one-horse, two-horse, and eventually even three-horse teams by the late 1920s [6:20].

Today, a similar process is unfolding across the energy landscape. Newer technologies like solar panels, wind turbines, and electric vehicles (EVs) are constantly improving and reducing their cost, incrementally displacing the economic viability of fossil fuel applications [6:32].

The result of this economic displacement is evident in the data. Fossil fuel energy demand has already peaked in key sectors, signaling that the structural decline has begun.

Sector	Year of Fossil Fuel Demand Peak (Video Source)
Industry	2014
Buildings	2018
Road Transport	2019
Power Sector	Expected 2025

The power sector's peak fossil fuel use is predicted to occur this year. Although data lags by ~18 months, so we won't know it has happened until we've passed it. Growth in new electricity demand is now being fully met by non-fossil sources [11:50], in part because it is the fastest way to bring new supply online. This widespread peaking across industrial, residential, and transport sectors shows that the shift is pervasive and self-reinforcing.

The Efficiency Advantage of Electrification

The fundamental driver of this displacement is a massive difference in energy efficiency. Fossil fuels must be combusted, which generates heat that must then be converted into useful work. This process is thermodynamically inefficient; as much as two-thirds of the energy put into the current system is wasted, often literally going up in smoke [9:16].

In contrast, the modern electricity-based system generates electricity directly and applies it to the device doing the work, for example, a solar panel charging an EV battery [8:55]. Electricity is a superior energy source because it is more efficient and highly "multi-deployable," meaning it can be used for any energy service imaginable, from heating water to running data centers [10:12]. A lump of coal, by comparison, has very limited deployment options. This efficiency premium is so significant that the world can expect to double or even triple its energy service demand, such as the amount of hot water used or miles driven, while simultaneously lowering overall primary energy demand [10:31]. This makes the transition a powerful economic and engineering upgrade.

Conclusion

The age of combusting commodities for heat is yielding to the age of efficient electrification. The economic case for newer technologies, such as EVs and renewables, is simply too compelling to ignore, gradually picking off incumbent fossil fuel competitors one by one. The peaks in fossil fuel demand seen across industry, buildings, and transport confirm that the transition is well underway. By recognizing the powerful, decade-long trends rather than being distracted by short-term volatility, we can appreciate the magnitude of this structural evolution toward a cleaner, more efficient energy system.

Reframing the Challenge: Why Less Global Energy Consumption Makes Life Better

Today, global primary energy consumption is approximately 640 exajoules (EJ). Keep that number in mind for later.

As we move to a renewable energy system, if we want all the same services that we have today, then, at first glance, we'll have to replace every bit of energy we use today with renewables, right? Surprisingly, no. A lot of the energy that we generate today does not go towards the purposes that we want; instead, it is used to maintain the systems or is simply wasted. Do you care if your home uses 4GJ or 8GJ annually to stay warm in the winter and cool in the summer? No, you just want a comfortable home and low energy bills. Okay, maybe a few of my readers also care about the number, but comfort and cost are more important to the majority of people.

In a mostly electrified energy system powered by 100% renewables, the energy required to provide equivalent services (e.g., transportation, heating, industry, and electricity) would be significantly lower. It could be potentially reduced by 40-57% compared to projected business-as-usual scenarios due to the inherent efficiencies of electrification. That's worth repeating: by going all-electric, we could cut our energy use in half! For instance, electric vehicles and heat pumps use far less energy per unit of service than combustion-based alternatives, and electrification eliminates the substantial energy currently wasted in extracting, refining, transporting, and burning fossil fuels (which accounts for about 11-13% of global energy use). As you can see in the image above, for a perolium-powered car, it takes 6 units of energy to get 1 unit of motion. An EV, on the other hand, only takes 1.2 units of energy for 1 unit of motion.

The waste and inefficiencies of the old system includes the vast fleets of crude oil tankers, massive vessels that crisscross oceans hauling billions of barrels of petroleum products, liquified natural gas, and other fossil fuels each year, as well as endless train cars loaded with coal rumbling across continents to power plants, both of which would become obsolete relics in a renewably-powered, electrically sourced world. A global transition to wind, water, and solar (WWS) energy, the all-purpose end-use energy demand could drop to around 280 EJ annually in a 2050 scenario, even with economic and population growth factored in. Adjusting for current service levels, this translates to roughly 230-280 EJ of renewable electricity generation needed, representing a major reduction from today's primary energy levels.

This savings embodies the concept of "negawatts," a term coined by energy expert Amory Lovins to describe units of energy conserved through efficiency improvements and smarter systems. Those negawatts effectively act as a "negative" demand that reduces the need for new generation capacity. In the context of the energy transition, negawatts could represent trillions of kilowatt-hours saved globally each year by shifting to efficient electric technologies, avoiding the build-out of unnecessary power plants and infrastructure.

Furthermore, distributed batteries (such as those in homes, electric vehicles, and community storage systems) could play a key role by buffering surplus renewable generation (e.g., excess solar during peak daylight) and delivering it on demand during low-production periods. This would minimize curtailment of renewables, enhance grid reliability, and further optimize the system, potentially reducing overall energy needs by enabling more precise matching of supply and demand without relying on fossil fuel peakers.

The global transition to a 100% renewable energy system is fundamentally an efficiency revolution. The initial, intimidating figure of 640 exajoules (EJ) of current primary energy consumption dramatically shrinks when viewed through the lens of electrification. By eliminating the vast energy waste inherent in extracting, refining, transporting, and burning fossil fuels, and by leveraging the superior efficiency of electric technologies like EVs and heat pumps, global end-use energy demand could realistically drop by ~ 50%. This shift reframes the challenge entirely, allowing us to meet all our modern service needs with an estimated 230 to 280 EJ of renewable electricity annually. This substantial margin represents the powerful economic and ecological benefits of "negawatts" of energy saved through smarter systems. When integrated with distributed battery storage to ensure grid stability and minimize curtailment, the pathway to a reliable, clean energy future becomes not just viable, but remarkably less resource-intensive than projected business-as-usual scenarios. The transition is not simply about finding new sources of energy, but about being drastically more intelligent with the energy we use as we move towards a future free from fossil fuels.

Goodbye to the Tesla Model S & X

Electric Pioneers Turn the Page: Fourteen Years of Model S and X Magic

Tesla changed the car game forever when it rolled out the Model S in 2012. Back then, electric vehicles still felt like science projects for the brave few. Fast forward to 2026, and custom orders for both the Model S and its sibling, the Model X, have wrapped up. As I write this, there are still a couple of hundred inventory units available, but they are going fast. Production at the Fremont factory is winding down now and will completely stop before the end of June 2026 to clear space for the next big thing. These flagships proved EVs could deliver luxury, serious range, blistering speed, and software smarts that improve with age. Their story spans fourteen years of clever engineering, bold bets, and steady progress toward a cleaner drive. We track every major step, from humble beginnings to graceful exit, with a special look at how the long-range, non-performance versions deliver better value today, even after inflation.

The Model S story kicked off way back in 2008 as the Project WhiteStar. Tesla aimed to build a full-size electric sedan that could crush expectations. Production started in June 2012 at the old NUMMI plant in Fremont, California. The first Signature Series cars rolled to customers that summer with a game-changing 17-inch touchscreen, self-presenting door handles, and over-the-air updates. Early models offered up to 300 miles of real-world highway range, aluminum bodies, and instant torque that made traditional sedans feel ancient. Owners loved the quiet cabin and the way the car felt like a rolling computer.

The Model X joined the family with a big reveal in 2012 alongside the S. Deliveries finally began in September 2015, after some tweaks to the falcon wing doors and production hiccups. The X shared the same electric bones but added SUV practicality, a massive panoramic windshield; five, six, or seven-seat layouts, and those dramatic doors. Both cars hit the road with technology far ahead of other automakers that still used push buttons and required dealer visits for software updates. Tesla showed the world that with OTA updates, vehicles could evolve long after purchase. Early awards poured in, sales climbed, and the Supercharger network started to make long trips feel effortless. These vehicles built the foundation for everything that followed.

Early Sparks and Steady Gains

The first few years brought exciting firsts. Autopilot hardware arrived in 2014 with basic driver assistance that felt futuristic. Dual motor, all-wheel-drive versions debuted in 2015 for better grip and quicker launches. By 2016, the Model S got a fresh front end, improved aerodynamics, and adaptive suspension options. The Model X followed with similar upgrades. Battery packs grew to 100 kilowatt hours, range crept higher, and thermal management got smarter for consistent performance in any weather.

Tesla celebrated the 100,000th Model S sold in 2015. Global expansion pushed the cars into more markets while the company refined manufacturing. These early models focused on proving the concept. Non-performance long-range variants served as the everyday heroes for families and commuters who wanted efficiency without the track-ready extras. Owners raved about the low running costs and the joy of never visiting a gas station again. It was clear Tesla had cracked the code on making electric driving desirable.

The Refresh Revolution: From 2019 to 2026

Bigger leaps came with the 2021 update that reshaped both vehicles. Tesla introduced a sleek new interior with a yoke steering option on the Model S, ventilated seats (again), and a more modern dashboard layout. A structural battery pack boosted rigidity and safety. Dual motor setups became standard on long-range models, while hardware advanced from HW3 to later AI4 camera systems. Range, acceleration, and charging speeds all jumped forward thanks to better motors, tires, and software tweaks. Adaptive air suspension smoothed the ride, and the Model X kept its signature doors with added refinement.

Continuous over-the-air improvements followed. Cabin noise dropped with extra insulation and active cancellation. Ambient lighting added flair, and a front bumper camera arrived in the final years for tighter parking maneuvers. By 2025 and early 2026, light updates included fresh wheel designs, dynamic lighting, and even more third-row space in the X. The long-range Model S now claims 410 miles of EPA range, a huge leap from the original 265 miles. Acceleration for non-performance dual motor versions improved to about 3.1 seconds zero-to-60. Charging rates climbed from early 120 kilowatt peaks to modern V3 and V4 stations that add miles per minute at impressive clips. Autonomy matured from basic Autopilot to supervised Full Self Driving capability. The Model S stayed the sporty sedan while the X offered family-friendly utility. Each update felt like getting a new car without buying one, thanks to that relentless tech momentum.

Signature Showdown: First versus Final

Compare the very first Signature Model S from 2012 to the final Signature Model S delivered in 2026. The original 2012 Signature packed an 85-kilowatt-hour battery, rear wheel drive, roughly 265 miles of range, and a 17-inch touchscreen. It felt revolutionary at launch.

The 2026 Signature version delivers a transformed machine. From first to last, the part count was reduced by 40%, and only about 3% of the original parts remain shared. The final car is 375 pounds lighter, around 40% more efficient, and boasts thousands of cumulative improvements across hardware and software. It features dual motors or tri motor Plaid options, up to 410 miles of range on the long-range model, a vastly quieter cabin, advanced AI hardware for autonomy, a modern yoke or steering wheel, multiple displays, adaptive suspension, front camera, and carbon ceramic brakes with gold calipers on the Signature edition.

From a big screen and basic over-the-air capability to full self-driving hardware, console-level gaming, record-breaking acceleration under 2 seconds, and industry-leading efficiency, the evolution is staggering. In the 14 years of Model S evolution, Tesla packed in about 60 years' worth of improvements compared to traditional auto manufacturers. That acceleration comes from vertical integration, rapid iteration, and fearless over-the-air deployment.

Price Tag Tango: How Value Soared

One of the most impressive parts of this journey shows up in the numbers. Tesla kept refining costs through scale and innovation. The long-range, non-performance models deliver far more today for less money in real terms. Check the table below for the inflation-adjusted story using US CPI data. It focuses on the US base long-range configurations before incentives.

Year	Nominal MSRP ($)	Inflation Adjusted to 2026 ($)	EPA Range (mi)	Key Features Added
2012	77,400	~110,200	265	17-inch touchscreen, OTA updates, RWD long-range pack
2016	85,000	105,000	270	AWD standard options, adaptive suspension
2021	79,990	92,000	390+	Yoke interior, structural pack, dual motor
2026	96,630	96,630	410	Front camera, quieter cabin, AI hardware

The adjusted price has fallen sharply, while the range grew over 50%, performance improved dramatically, and autonomy features expanded. That's real progress. Buyers get a quieter, safer, smarter car for fewer real dollars. Tesla proved that scale and software can bend the value curve in favor of drivers who want to leave fossil fuels behind.

Milestones That Made History

Tesla celebrated the end with a commemorative video highlighting the incredible achievements of the Model S and Model X. Over 750,000 of these vehicles found homes worldwide. They were the first cars with Full Self Driving hardware and the first with console-level gaming. The Model S became the first EV to surpass 400 miles of range and the first production car to hit 0 to 60 MPH in under 2 seconds while breaking quarter mile records. It earned Motor Trend Car of the Year and even recognition as one of the best cars of the last 70 years. The Model X stood out as the quickest production SUV ever and the first SUV to avoid rolling over in safety tests. Together, the duo helped avoid more than 20 million metric tons of CO2 emissions (and growing). These records underscore their pioneering spirit and lasting impact.

Final Farewell and Factory Farewell

Production wraps up in the second quarter of 2026 after Elon Musk called it an honorable discharge. Custom orders closed earlier this year. The factory space shifts toward robotics and future projects. It feels bittersweet, yet the move signals confidence in what comes next. Owners of existing cars can still count on software updates and Supercharger access for years ahead. The final units represent the pinnacle of fourteen years of refinement.

Legacy Lives On: Paving the Path to a Future Free from Fossil Fuels

These cars did more than win awards. They forced the entire industry to accelerate electrification and showed that EVs could match or beat luxury rivals in every way that matters. Long-range electric driving turned practical. The Model S and Model X started as bold experiments and ended as proven legends. Their DNA lives in every Tesla that followed, and their success helps push us all toward a future free from fossil fuels. If you snag one of the last units or already own one, enjoy the ride. The journey continues, and, if we're lucky, we just might see a new version of these vehicles someday. At CarsWithCords.net we remain long Tesla (and EVs in general) and are thrilled to have chronicled every mile.

Hello Heat Pump, $700 Savings in Year One

Heating Up the Hypothesis

Let's talk about home heating. It isn't the most glamorous topic. It is, however, incredibly important for both our wallets and the environment. We just completed our first winter with a heat pump, and we'll share the results here. We previously used a traditional natural gas furnace. I should clarify my terminology; "fossil gas" is a more accurate term than natural gas, so we'll use fossil gas for the rest of this discussion. The fuel primarily comes from ancient decomposed organic matter, after all. In the summer of 2025, we swapped out that old air conditioner for a sleek new heat pump. We still have a gas furnace, but now it only has to fire up on the coldest few hours of the winter, rather than running daily for 6 months of the year.  We tracked everything meticulously to compare the before-and-after. The data is fascinating. Let's dive in.

Wild Winter Weather Variations

We must acknowledge the weather. The weather always plays a big role in home heating. The winter of 2024/2025 was quite mild, and among the warmest we've had here in decades. The winter of 2025/2026 was even warmer. The best A/B test for a heat pump would be two very similar homes right next to each other, measured over the same winter. Here we have the second-best, a year-over-year comparison of the same house. Also, to this list of caveats, we must add that this analysis looks at our complete gas and electricity bills. It is not limited to just the electricity used by the heat pump or the fossil gas just used by the furnace, although these are the largest consumers of these resources in our home.

Winter 2025/26 set record highs in the US Pacific Northwest. We saw average temperatures hovering in the high 40s and low 50s F. We saw absolutely zero snow in the Willamette Valley. This warm weather undoubtedly helped our new heat pump perform efficiently. Heat pumps love mild winters. They pull ambient heat from the outside air. They compress it, and they pump it inside. Warmer outside air means less heating is needed and less work for the compressor.

Tracking the Therms and Watt-hours

Let's look at the raw numbers. We tracked our energy usage from October through April for both winters. The data shows a shift in our energy consumption. We saw a small increase in electricity use and a massive drop in fossil gas consumption. 

We used 668 therms of fossil gas during the 24/25 winter. We used only 124 therms during the 25/26 winter. That is an 81% reduction in fossil gas usage. We stopped burning things to stay warm on all but the coldest hours. Our electricity usage did go up. Heat pumps run on electricity. We used 7,522 kWh of electricity in 24/25. We used 9,336 kWh in 25/26. This is only a 24% increase in electrical consumption. 

In the 24/25 winter, our furnace ran for about 700 hours. Compared to our most recent winter, when it was just the heat pump backup, the furnace only ran for 60 hours. That's more than a 90% reduction.

Energy Big Picture Totals

To see the energy big picture, we'll convert the kWh and the therms to a common unit. We'll use gigajoules for this comparison. We used 98 gigajoules of total energy in the 24/25 season. We used only 47 gigajoules in the 25/26 season. That is a total energy reduction of 52%.

Metric	2024/2025 Winter	2025/2026 Winter	Change
Fossil Gas (Therms)	668	124	-81%
Electricity (kWh)	7,522	9,336	+24%
Total Energy (Gigajoules)	98	47	-52%

Financial Facts and Frivolity

The engineering is beautiful. Cutting our home's total energy use in half is amazing. It shows how efficient heat pumps are. They don't create heat. They just move it around. A completely different method from combustion. Efficiency is only part of the story. We live in the real world. We care about the monthly bills. Upgrading HVAC systems is expensive. We need to see a return on that investment. In our case, the financial results are highly encouraging. We saved a lot of money on our utility bills. The total savings for the winter came out to $701.67 USD. Keeping an extra $700 in the bank is a clear win. This shows that environmentally conscious choices can also be fiscally responsible. The upfront cost of the heat pump was high, but the AC needed to be replaced, and we received incentives from our state and utility. The operational savings will slowly repay that initial investment, and it means that we'll have lower utility bills every month going forward. This makes budget planning easier.

Experience and Engineering

It's more than CO2 reduction and lower bills; it's also a better daily experience. Our home felt comfortable all winter. Heat pumps provide a steady, consistent level of warmth. Old furnaces tend to blast hot air and then shut off. This creates noticeable too hot, too cold temperature swings. The heat pump, on the other hand, runs low and slow. It maintains a constant temperature without the dramatic spikes. We have an "inverter-driven" system. This means that the heat pump can operate anywhere from 40% to 100%. This keeps the temperature in the sweetspot for much more of the day, avoiding the big spikes. We're thrilled with the performance.

We're utilizing the basic principles of thermodynamics. We're capturing heat energy that already exists in the environment. A heat pump can do this even when it feels cold outside. There is still plenty of thermal energy in 40-degree (F) air. The heat pump concentrates it and delivers it to our living room. 

Practical Progress and Pragmatism

Heat pumps are fantastic machines. They aren't magic bullets, however. A heat pump is only as clean as the electricity that powers it. The US grid is slowly getting cleaner. We're adding more wind, solar, and hydroelectric power every year. As the grid cleans up, heat pumps become even better for the environment. Fossil gas furnaces will always burn fossil gas. An electric appliance improves its emissions profile as the power plant improves. Societal evolution is a slow, grinding process. We can't overhaul our entire infrastructure in a single year. We can make smart choices when old appliances break. If you install solar (or use community solar), your heating and cooling are powered by the sun, and it's insulated from changes in electricity prices. 

Concluding the Climate Calculation

Our winter experiment was a resounding success. We tested the technology under real-world conditions. We slashed our total energy consumption by 52%. We achieved an impressive 81% reduction in fossil gas usage. We also saved a nice chunk of change. Keeping an extra $700 is a good feeling. The transition was seamless. Our home was more comfortable than ever. The engineering is sound. We're realistic about the challenges ahead. Upgrading home infrastructure is expensive. Every newly installed heat pump is a step in the right direction. We're steadily marching toward a future free from fossil fuels.

The Race of Two Tipping Points - Renewable Adoption vs Global Warming

We now face a pivotal race between two types of non-linear changes. On one side are the catastrophic negative tipping points, such as the collapse of major ocean currents or the widespread thaw of permafrost. On the other is the highly encouraging positive tipping point of the economic dominance of renewable energy and energy storage.

The concept of "tipping points" has become central to our discussion of climate. These are thresholds where a small perturbation can push a large system into a completely new state, a change that is often self-propelling and difficult to reverse on human timescales. Our current global situation is defined by a race between two types of these tipping points: one, the destructive release of green house gasses, we desperately need to avoid, and, two, a transformative positive transition to renewable energy.

The Nature of Non-Linear Risk

The most worrying environmental tipping points are defined by their non-linear nature; they do not unfold gradually. By the time we notice the shift, it may already be too late to prevent the self-reinforcing state. Many of these critical Earth systems are estimated to be at risk of tipping at or just above 1.5°C of global warming, a threshold the planet has recently crossed for a full calendar year.

Among the systems causing the greatest concern is the Atlantic Meridional Overturning Circulation, or "AMOC." This is a massive oceanic conveyor belt that transfers an unimaginably large amount of heat across the equator. A significant slowdown or collapse of the AMOC would have dramatic consequences, including making winters in Western Europe significantly colder and potentially shifting the Intertropical Convergence Zone, which governs the monsoon seasons in India and West Africa. Such a shift threatens the food security and water supply for billions of people.

We also face risks from the vast cryosphere. The West Antarctica Ice Sheet alone holds enough ice to raise global sea levels by about five meters, and once a melt is underway, it is incredibly hard to stop. Similarly, the thawing of Arctic permafrost that holds approximately twice the amount of carbon currently in the atmosphere. This risks releasing enormous volumes of greenhouse gases, initiating a dangerous warming feedback loop. Finally, scientists believe the tipping point for warm water coral reefs may have already passed, with predictions showing that 70 to 90 % of these vital ecosystems could die in the coming decades.

The Economic Tipping Point: Renewable Power

Amidst these serious environmental challenges, the good news is that we have almost certainly crossed a powerful, positive tipping point: the economic dominance of renewable energy. For the first time in history, clean electricity generation is often the cheapest form of new power in most of the world.

This shift is rooted in something called Wright's Law (Swans' Law or the Learning Curve), which states that technology becomes cheaper as we build more of it. Solar power, in particular, has seen a "learning rate" of around 20%, meaning that every time global solar capacity doubles, the cost falls by roughly 20%. Since 1976, the cost of solar has dropped by over 99%. This dramatic decline makes a compelling case for transitioning away from legacy fossil fuel systems! In fact, in roughly half the world, it is now financially sound to shut down an existing fossil fuel plant with life left in it and replace it with brand new renewables and battery storage.

The following table summarizes the dual nature of our current tipping point predicament:

Tipping Point System	Nature of Shift	Key Consequence
Atlantic Meridional Overturning Circulation (AMOC)	Negative, Climatic	Dramatic cooling in Europe, monsoon system disruption
West Antarctica Ice Sheet	Negative, Climatic	Multiple meters of irreversible global sea-level rise
Solar Power Generation	Positive, Economic	Cheapest source of new electricity (over 99 % cost drop)

This positive change is scaling globally, offering access to reliable electricity for millions of people in places like sub-Saharan Africa and driving rapid expansion in economies like India. Globally, over 90 % of new electricity capacity being built is clean energy, confirming the market has decidedly tipped.

Winning the Race

The positive tipping point is clearly underway, but the window to benefit from it is closing rapidly. This is fundamentally a race against time. The market is now driving the transition, but policy and investment are needed to accelerate it fast enough to avoid the worst consequences of the negative tipping points.

We see this tension in the continuing high levels of fossil fuel subsidies, which are almost nine times higher globally for oil and gas than for renewables. Furthermore, while countries like China are on track to become a global "electro-state," leading the world in manufacturing and deploying clean energy, the US risks being left behind by doubling down on oil and gas exports.

Ultimately, the technical and economic barriers to a sustainable future have largely dissolved. The path forward now depends on a clear-eyed commitment from governments, industries, and individuals to leverage the massive economic opportunity that the renewable energy tipping point provides. If we focus our resources on accelerating this positive shift, we have the best possible chance of navigating the critical moment we are in, and tipping the scales toward a safer, more stable future.
